Any good resources to learn blue teaming?

I have little experience in cybersecurity and the IT field in general but I am curious what the best resources are out there for improving your foundation and knowledge for the blue team. I went through the cyber defense learning path in tryhackme but it seems it just gives you an overview on important concepts to learn for the blue team but it does not seem to really go in depth. Is reading the sec+ textbook a good start?
